Dynamics of Blood Values in Patients with Radial Shaft Injury after Using Transosseous Osteosynthesis by external Fixation Pin Device

At the dental reception, complications after dental implantation in the form of mucositis and peri-implantitis are becoming more and more common. There are quite a lot of risk factors for the development of inflammation of the parotid tissue, there is no single idea about the etiopathogenesis of the above pathology. Mucositis refers to the initial stage of peri-implantitis development and is reversible. The specialist should promptly diagnose the development of the inflammatory potential and start treatment, in order to prevent the development of bone destruction around the implants. One of the methods of local exposure to the lesion is ozone therapy.Goal. This paper describes the method of treatment of peri-implantation mucositis by ozone therapy.Materials and methods. In patients with peri-implantation mucositis, the inflammatory peri-implantation tissue was ozonated directly in the oral cavity with the Ozotron device in order to relieve inflammation and improve microcirculation in the oral cavity. Before performing oral ozonation, all patients underwent a general clinical examination to identify contraindications to this method. It also describes in detail the scheme that prevents the penetration of ozone into the body and prevents its ingestion.Results. During ozonation, a positive trend was obtained in the treatment of post-prosthetic complications during dental implantation. The developed scheme of ozonation in the oral cavity stops the inflammation of the peri-implantation tissue. Side effects and complications during ozone therapy directly in the oral cavity were not detected.Conclusions. The inclusion of ozone therapy in the treatment regimen of patients with peri-implantation mucositis is an appropriate and justified physiotherapy method.

A special place in the methods of surgical treatment of bone fractures is occupied by transosseous osteosynthesis using external fixation devices of various designs.Objective: to analyze the lower jaw exoskeleton in finite element programs.Materials and research methods. During the research, 36 human lower jaws were involved from the museum of the Department of Oper-ative Surgery and Topographic Anatomy of the Volgograd State Medical University. They were scanned in 3D. All obtained images were loaded into a virtual scene reconstruction program. Fractures of the lower jaws in the corner area were modeled, an apparatus for external fixation of the lower jaw exoskeleton was installed, and the chewing load on the lower jaw was simulated. The place of application of the force was an area on a small fragment of a repositioned 3D model of the mandibular bone corresponding to the place of attachment of the masseter muscle. The evaluation of virtual studies was carried out according to the results of the stress-strain states of the bones and apparatus, the schedule of displacements of objects and the results of the analysis of the safety factor.Research results and discussion. In the course of evaluating the virtual placement of the mini-fixator wires of the apparatus for external fixation of the lower jaw exoskeleton, it was revealed that the main load is applied to the mini-fixator wires on a large fragment and the bone in the area of the wires. For the possibility of precise positioning of the osteofixers of the external fixation device, a device for the safe installation of the spokes of the lower jaw exoskeleton was also developed.Conclusion. Thus, on the basis of computer mathematical analysis, it can be argued that the developed design of the apparatus for external fixation of the lower jaw exoskeleton works under conditions of the maxillofacial region, performs reposition and fixation of bone fragments of the lower jaw under conditions of chewing functioning of the restored fracture of the lower jaw.
